PIERRE, S.D. (MITCHELLNOW) New spring weight restrictions are in effect along South Dakota’s roadways this week.  They’re put in place by the state Department of Transportation and local agencies. Updated restrictions will be in place March 10th through 14th to protect roads as thawing and melting snow saturate softened ground, causing roadbeds to be more susceptible to damage. A map of the restrictions is on the South Dakota Truck Info website at SD-Truck-Info-dot-sd-dot-gov.
